Document Summary

Closed system: a system separated from its surrounding by a physical boundary in which chemical changes can be studied. Dynamic equilibrium: a balance between the forward and reverse processes in a closed system. Forward reaction: a left-to-right movement of reaction ( ) reverse: a right-to-left movement of reaction( ) Solubility equilibrium: a dynamic equilibrium between a solute and a solvent in a saturated solution in a closed system. A dynamic equilibrium between different physical states of a pure substance in a closed system. e. g. h2o(s) h2o(l) t = 0oc. A dynamic equilibrium where the concentrations of all reactants and products remain constant with time in a closed system. When the rate of regeneration of the reactants is equal to the rate of consumption of the reactants, then the system will be in a state of equilibrium. Rate of forward (micro activities continues) rate of reaction does not reach zero at equilibrium.
